The device is quite impressive by its dimensions and quite heavy (about 11 kg). Well, 10A at 30V - stuck since a lot has to transformer in it.
Commissioning is simple. (Fine and coarse) settings are also easy by two controllers, each for voltage and current. The display is easy to read. The processing is at first glance very good and also the materials are stable. The entire casing is made of metal / metal, only the iris + knobs are made of plastic.
A German manual was there, as well as a pair of strands with clamp on the connection sockets on the device. An IEC connector (220V) is doing anyway.
In operation, an internal fan is switched on at a certain load or heat, but which does not always run and also causes little noise. (Comparable PC Power Supply)
Overall for this price an absolute recommendation.
